The world’s largest flawless vivid blue diamond sold for $24 million at a Christie’s sale in Geneva on May 14 – setting a new world auction record for the price per carat for a blue diamond.

Just a day after Sotheby’s sold a 100-carat flawless yellow diamond for $16.3 million, came the sale of the 13.22 carat rock known simply as “The Blue“.
The US jeweller Harry Winston bought the blue diamond, and immediately after the sale, it was renamed into ‘The Winston Blue’.

Christie’s next Magnificent Jewels sale will be held in Hong Kong on May 27. Headlining it is a rare Golconda diamond pendent necklace named The Eye of Golconda, whose centrepiece is the largest Golconda-mined diamond ever to be auctioned in Asia.
